## org.springframework.context.support
Class ResourceMapFactoryBean

    java.lang.Object
      org.springframework.core.io.support.PropertiesLoaderSupport
          org.springframework.beans.factory.config.PropertiesFactoryBean
              org.springframework.context.support.ResourceMapFactoryBean

All Implemented Interfaces:
  FactoryBean, InitializingBean, ResourceLoaderAware

    public class ResourceMapFactoryBean

extends PropertiesFactoryBean
implements ResourceLoaderAware

FactoryBean that creates a Map with String keys and Resource values from properties, interpreting passed-in String values as resource locations.

Extends PropertiesFactoryBean to inherit the capability of defining local properties and loading from properties files.

Implements the ResourceLoaderAware interface to automatically use the context ResourceLoader if running in an ApplicationContext. Uses DefaultResourceLoader else.

Since:
  1.0.2

Constructor Detail

### ResourceMapFactoryBean

    public ResourceMapFactoryBean()

Method Detail

### setResourceBasePath

    public void setResourceBasePath(String resourceBasePath)

  Set a base path to prepend to each resource location value in the properties file.

  E.g.: resourceBasePath="/images", value="/test.gif" -> location="/images/test.gif"

### setResourceLoader

    public void setResourceLoader(ResourceLoader resourceLoader)

  Description copied from interface: `ResourceLoaderAware`
  Set the ResourceLoader that this object runs in.

  This might be a ResourcePatternResolver, which can be checked through `instanceof ResourcePatternResolver`. See also the `ResourcePatternUtils.getResourcePatternResolver` method.

  Invoked after population of normal bean properties but before an init callback like InitializingBean's `afterPropertiesSet` or a custom init-method. Invoked before ApplicationContextAware's `setApplicationContext`.

  Specified by:
    `setResourceLoader` in interface `ResourceLoaderAware`
  Parameters:
    `resourceLoader` - ResourceLoader object to be used by this object
  See Also:
    `ResourcePatternResolver`, `ResourcePatternUtils.getResourcePatternResolver(org.springframework.core.io.ResourceLoader)`

### getObjectType

    public Class getObjectType()

  Description copied from interface: `FactoryBean`
  Return the type of object that this FactoryBean creates, or `null` if not known in advance.

  This allows one to check for specific types of beans without instantiating objects, for example on autowiring.

  In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.

  This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.

  NOTE: Autowiring will simply ignore FactoryBeans that return `null` here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.

  Specified by:
    `getObjectType` in interface `FactoryBean`
  Overrides:
    `getObjectType` in class `PropertiesFactoryBean`
  Returns:
    the type of object that this FactoryBean creates, or `null` if not known at the time of the call
  See Also:
    `ListableBeanFactory.getBeansOfType(java.lang.Class)`

### createInstance

    protected Object createInstance()
                             throws IOException

  Create the Map instance, populated with keys and Resource values.

  Overrides:
    `createInstance` in class `PropertiesFactoryBean`
  Returns:
    the object returned by this factory
  Throws:
    `IOException` - if an exception occured during properties loading
  See Also:
    `PropertiesLoaderSupport.mergeProperties()`

### getResource

    protected Resource getResource(String location)

  Fetch the Resource handle for the given location, prepeding the resource base path.

  Parameters:
    `location` - the resource location
  Returns:
    the Resource handle
  See Also:
    `ResourceLoader.getResource(String)`
